Detailed Description
The present application will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The embodiment of the application provides a multi-BMC communication method, device and equipment and a computer storage medium. First, a multi-BMC communication method provided in an embodiment of the present application is described below.
Fig. 1 shows a flowchart of a multi-BMC communication method according to an embodiment of the present application. As shown in fig. 1, the method may include the steps of:
s110, the master BMC sends heartbeat request information to the plurality of slave BMCs in turn.
The multi-BMC server system can effectively reduce the load of a single BMC, and improve the management efficiency and the running stability of the server. The multi-BMC server system comprises a master BMC and a plurality of slave BMCs, wherein each slave BMC is connected with a plurality of components, and the components can be network cards, power supplies and the like. Each slave BMC monitors the health condition of the components connected with the slave BMC, and the master BMC monitors the working condition of the slave BMC to acquire the health condition of the components. The multiple BMCs jointly undertake the monitoring function of the health states of different components of the whole server system, and can manage and monitor the operation and the health states of all the components more accurately and finely.
After the system is powered on, the master BMC sends heartbeat request information to the plurality of slave BMCs in a polling mode, wherein the heartbeat request information comprises information such as temperature, voltage, current, alarm and health state which are requested to be acquired. And after receiving the heartbeat request information from the BMC, responding according to the heartbeat request information, generating response information, and returning to the main BMC.
And S120, judging whether the master BMC and the slave BMC establish communication or not based on response information returned by the slave BMC according to the heartbeat request information.
If the master BMC and the slave BMC establish communication, the response information comprises response information of the request content of the heartbeat request information, and if the master BMC and the slave BMC do not establish communication, the response information comprises state information of failure in execution of the heartbeat command, or the heartbeat request information of the master BMC is not responded.
And according to response information returned by the slave BMC according to the heartbeat request information, whether the communication between the master BMC and the slave BMC is established can be known.
And S130, when communication between the master BMC and the slave BMC is established and communication is abnormal, sending heartbeat request information of preset times to the slave BMC.
On the basis that the master BMC and the slave BMC establish communication, the master BMC initiates a heartbeat request at intervals, and the slave BMC replies to the master BMC in time after receiving the request. After receiving the response message, the master BMC may repeat S120 to determine whether the current communication is normal. If the communication is normal, the master BMC sends time data, configuration information and the like to the slave BMC to synchronize the master BMC with the slave BMC.
If the communication between the master BMC and the slave BMC is abnormal, the master BMC cannot immediately disconnect the communication with the slave BMC. In order to avoid instant communication abnormality and influence on data interaction of the whole system, heartbeat request information of preset times is sent to the slave BMC. According to actual operation, the experiment effect is good when the preset times are 8-12, wherein the effect is best when the preset times are 10.
And S140, determining the communication state of the master BMC and the slave BMC based on response information returned by the slave BMC according to the heartbeat request information received each time.
The slave BMC responds to return a response message or no response every time the master BMC sends a heartbeat request message to the slave BMC. The master BMC can judge whether the communication state of the master BMC and the slave BMC is normal or abnormal according to the response information.
It can be seen that, in the embodiment of the present application, heartbeat request information is sent to a plurality of slave BMCs in turn by a master BMC, whether communication is established between the master BMC and the slave BMCs is determined based on response information returned by the slave BMCs according to the heartbeat request information, when communication is established between the master BMC and the slave BMCs and communication is abnormal, communication is not immediately disconnected, but heartbeat request information of preset times is sent to the slave BMCs, so that communication jitter is prevented, and based on response information returned by the slave BMCs according to heartbeat request information received every time, the communication state between the master BMC and the slave BMCs is determined, so that the stability of communication between the multiple BMCs is improved, and thus the validity and timeliness of data interaction between the multiple BMCs are ensured.
The steps in the above-described process flow are described in detail below. First, the above-mentioned S140, namely, "determining the communication status between the master BMC and the slave BMC based on the response information returned by the slave BMC according to the heartbeat request information received each time" will be described in detail with reference to the embodiments.
As an implementation manner, according to the response information, determining heartbeat request results of the master BMC and the slave BMC, wherein the heartbeat request results comprise request failure and request success;
and when the heartbeat request result is that the times of request failure are smaller than the times of request success of the heartbeat request result and the heartbeat request result of the response information corresponding to the last heartbeat request information is that the request is successful, or when the heartbeat request result of the response information corresponding to each heartbeat request information is that the request is successful, determining that the master BMC and the slave BMC are normally communicated.
And if the response information is empty, or the response information comprises state information of heartbeat command execution failure, determining that the heartbeat request results of the master BMC and the slave BMC are request failure, and if the response information comprises response information of the request content of the heartbeat request information, determining that the heartbeat request results of the master BMC and the slave BMC are request success.
Taking the preset number of times as 10 times as an example, when the number of times of request failure is smaller than the number of times of request success, and the heartbeat request result of the response message corresponding to the last heartbeat request message is the request success, that is, the probability of request success is more than 50%, and the last heartbeat request is successful, it is determined that the master BMC and the slave BMC are in normal communication.
And determining that the master BMC and the slave BMC are in normal communication, and the master BMC keeps the current normal data interaction.
As an implementation manner, when the heartbeat request result is that the number of times of request failure is greater than the number of times of request success, or when the heartbeat request result of the response message corresponding to the heartbeat request message is a request failure each time, it is determined that the master BMC and the slave BMC are abnormal in communication.
If the probability of success of the request is less than 50%, or if 10 heartbeat requests fail, then it is determined that the master BMC is out of communication with the slave BMC.
As an implementation manner, if the probability of success of the request is lower than 50%, or the heartbeat requests of the preset times fail, the heartbeat request information is sent to the slave BMC at preset time intervals;
judging whether the master BMC and the slave BMC establish communication or not based on response information returned by the slave BMC according to the heartbeat request information;
if the communication between the master BMC and the slave BMC is not established within the preset time range, the slave BMC is determined to be the abnormal slave BMC;
alarm information about the exception from the BMC is sent to the user.
After the communication between the master BMC and the slave BMC is abnormal, the master BMC continues to send heartbeat request information to the slave BMC at intervals of a preset time period, and whether the master BMC and the slave BMC establish communication is continuously judged according to response information returned by the slave BMC according to the heartbeat request information until the communication is normally established again. The preset time period may be 1 second, 2 seconds, 3 seconds, and the like, but the smaller the value of the preset time period, the better.
The preset time range can be set to be 5 minutes, if the communication between the master BMC and the slave BMC is not established for more than 5 minutes, the slave BMC is determined to be the abnormal slave BMC, and the alarm information about the abnormal slave BMC is generated according to the abnormal situation. And triggering a main BMC communication abnormity alarm mechanism, reporting alarm information to a user so that the user can find abnormity in time for maintenance, recovering the normal operation of the server system as soon as possible, and ensuring the stability of the server system.
As a realizable way, after sending the alarm information to the user, the heartbeat request information is sent to the plurality of slave BMCs in turn, so that the communication is automatically established after the user overhauls the abnormal slave BMCs.
After the master BMC triggers the communication abnormality alarm, the master BMC does not stop sending the heartbeat request, but keeps polling and sending heartbeat request information, and repeatedly executes S110 and S120 until the communication is normally established, and the master BMC releases the alarm and informs the user.
The above step S120, that is, determining whether the master BMC and the slave BMC establish communication based on the response information returned by the slave BMC according to the heartbeat request information, will be described in detail with reference to the embodiment.
As an implementation manner, whether the master BMC and the slave BMC establish communication is determined based on status bit information returned by the slave BMC according to the heartbeat request information.
The response information includes status bit information including a field value for indicating success or failure in execution of the heartbeat command.
If the status bit information includes 0x00, indicating that the master BMC and the slave BMC have established communication, the data interaction is normally performed. If the status bit information includes other abnormal values such as 0xd5 and 0x83, it indicates that the master BMC and the slave BMC do not establish communication, sends heartbeat request information to the slave BMC again, and checks the status of the slave BMC according to the status bit information in the response information returned by the slave BMC until the master BMC and the slave BMC normally communicate. In addition, if the master BMC does not receive the response message from the slave BMC, the master BMC repeatedly sends the heartbeat request message to the slave BMC again.
According to the embodiment of the application, when the master BMC and the slave BMC are abnormal, the master BMC sends heartbeat request information to the slave BMC for multiple times to determine the communication state of the master BMC and the slave BMC, so that the instant communication abnormality is avoided, and the communication anti-shaking is realized. And in a preset time period, sending alarm information to the user by abnormal communication to remind the user of timely maintenance. The master BMC sends heartbeat request information to the slave BMC in a polling mode, and can establish connection in time after abnormal recovery of the slave BMC so as to guarantee validity and timeliness of data interaction among multiple BMCs, stably monitor the health state of the server, stably manage services in real time and further guarantee stable operation of the whole server.
With reference to the implementation manner in the foregoing embodiment, a preferred method flow provided by the embodiment of the present application is described below with reference to fig. 2 by way of example. As shown in fig. 2, the method may include the steps of:
s201, the master BMC sends heartbeat request information to the plurality of slave BMCs in turn.
S202, whether the master BMC and the slave BMC establish communication is judged based on the status bit information returned by the slave BMC according to the heartbeat request information.

And S203, sending the time data and the configuration information to the slave BMC.
And S204, sending heartbeat request information of preset times to the slave BMC.

And S206, when the heartbeat request result is that the times of request failure are smaller than the times of request success of the heartbeat request result, and the heartbeat request result of the response information corresponding to the last heartbeat request information is that the request is successful, or when the heartbeat request result of the response information corresponding to the heartbeat request information each time is that the request is successful, determining that the communication between the master BMC and the slave BMC is normal.
And executing S203 when the communication between the master BMC and the slave BMC is normal.
And S207, when the heartbeat request result is that the frequency of request failure is greater than the frequency of request success, or when the heartbeat request result of response information corresponding to the heartbeat request information is that the request fails, determining that the communication between the master BMC and the slave BMC is abnormal.
And when the communication between the master BMC and the slave BMC is abnormal, executing S208.
And S208, sending heartbeat request information to the slave BMC at intervals of preset time intervals.
S202 is performed based on response information returned from the BMC according to the heartbeat request information. If the master BMC and the slave BMC have established communication, S203 is performed, otherwise, S209 is performed.
And S209, if the communication between the master BMC and the slave BMC is not established within the preset time range, determining the slave BMC as the abnormal slave BMC.
S210, alarm information about the abnormal slave BMC is sent to the user.
After the warning information is transmitted to the user, S201 is continuously performed.
The technical effects achieved by the above-mentioned S201-S210 are the same as the technical effects achieved by the S110-S140, and are not described herein again.
